Transformation Ratio Test Equipment for Z Type Transformer
TTR-Z Transformation ratio test equipment is specially designed for three- phase transformer in power system, especially for transformer of type Z winding and other transformers whose zero-load current is relatively high. The tranformation ratio test equipment has wide testing range, fast testing speed, favorable repeatability, flexible data processing, convenient connection, complete protection, easy learning and convenient operation.
1 This transformation ratio test equipment is applicable to transformers connected in Z type.
2 Two output voltages are optional and applicable to transformer whose zero-load current is relatively high.
3 This Transformation ratio test equipment has wide testing range and the highest transformation ratio may reach 10000.
4 Automatically calculate tap position.
5 Fast speed, which is only 18 seconds for three-phase
6 Favorable repeatability.
7 Automatically save 99 data at most.
8 Flexible data processing, including retrieval, print, transfer to U-disk, delete and upload to PC computer for testing.
9 Have transformer short-circuit protection and interturn short-circuit protection functions. In case of short circuit, relevant information will be displayed on the LCD screen in characters.
10 The upper computer could control the whole testing process, save data .
11 Struction manual is attached to the tester, providing convenience for users.
12 The ttr turns ratio tester is small and is a little bigger than a piece of A4 paper.
13 The transformer turns ratio tester is light and its weight is only 6.9kg.
